The effects of palm oil fatty acid and stearic acid on dynamic properties, curing characteristics and mechanical properties of carbon black filled epoxidized natural rubber compounds were studied. It was found that the scorch time, t2 and cure time, t90 increased with increasing both acids concentrations. For dynamic properties, the maximum elastic torque, increased with acids concentration, whereas the minimum elastic torque shows a decreasing trend. Results also indicate that the decrease in viscous torque and tan δ is significant with increasing acids concentration. For tensile modulus, hardness, maximum torque-minimum torque and swelling index, results indicate that both acids have some effects on crosslink density. However tensile and tear strength pass through a maximum as the concentration of both acid increased.
